Help with Icepower 1200as2 amp please!

Hello everyone! I am having an issue with my Icepower 1200as2 module. I have ran this amp for a few years and all of a sudden it starts going into a standby mode, then comes back on for a little while, then back to standby even when a signal is passing through. When I first built this DIY project using the 1200as2 module, I hooked up 2 LEDS on the front of the chassis. When first powering up the amp, the amber LED would light up until a signal was picked up through the RCA interconnects circuitry?  So if I wasn't playing anything through the amp, the amber LED would light up and stay on until a signal was detected. I really don't want to trash the module, so if I can get some help to perhaps fix this issue, I'd be very grateful and appreciative! Thanks for any help!

Best,

Jacques

I did list my issues with this amp module on DIY forum. Haven't had much of a response though :(  I have disconnected the P101 connector and tried to see what happens and a few minutes of playing, it starts that same annoying switching back and forth from ON to Standby. The noise I hear is not really just a click sound rather a combo of what appears to sound like a click with a voltage type of noise. It's just does it fast then stops. I had noticed this noise/sound when I first hooked up my amp to play. I just feel that I'd hate to trash it. Maybe someone can come up with a trouble shooting idea I can try to resolve this issue. But perhaps it may be something I can't fix! Perhaps if I can't fix it, I can look to build another amplifier using my enclosure/chassis and RCA connectors, speaker binding post, etc. I was looking at some other amps/kits using the Purifi components? I was also told to look at these components: Hypex Ncore, NcoreX, Nilai, Purify Eigentakt, and I believe the NCxMP version will be out soon? Any suggestions? Thanks again Erik!

I have taken a photo of the module where I am hearing this clicking/voltage sound. I'm not sure which component it is though, and not sure where I could begin to probe!

OP:
 

It sounds like you are a beginner to this and this may be a bad way to get your feet wet.  Please be careful as there are some lethal voltages in there. 

Honestly I wish you'd learn more from other projects than this one. 

Best,

Erik is right, one of those components is labeled 305 volts ac! Donget zapped, it's not as fun as Scott Baio made it look 🙂

While I appreciate the comments, I wouldn't call myself a beginner! I'd never start messing around with any electrical component, especially while live, unless I was absolutely positively certain I knew a little something about it. I'm not saying I have a degree in electronics, or otherwise I wouldn't be asking for some help or guidance with troubleshooting this amp module. I just thought that perhaps someone here may have had some experience with the issue I am having with my ice amp, that would be willing to give me some guidance. But I do appreciate you guys for trying to help out!
